Genes affected

HIBADH (HGNC:4907): (3-hydroxyisobutyrate dehydrogenase) This gene encodes a mitochondrial 3-hydroxyisobutyrate dehydrogenase enzyme. The encoded protein plays a critical role in the catabolism of L-valine by catalyzing the oxidation of 3-hydroxyisobutyrate to methylmalonate semialdehyde. [provided by RefSeq, Nov 2011]

HIBADH Gene-Disease associations (from GenCC):

• 3-hydroxyisobutyric aciduria

  Inheritance: AR Classification: LIMITED Submitted by: ClinGen
• inborn organic aciduria

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0778 is higher than 0.05.
